I can't see a square or a D given with your question.

But to find the perimeter you just have to add the surface of every side of the square.

If f(x) = 3x - 5, than f(2) =

Mamont248 [21]

If we substitute 2 into x it'll be:

$3x - 5 \\ 3(2) - 5 \\ 6 - 5 \\ 1$

Solve: 2x+3y=1<br> y=-2x+11

Sauron [17]

Answer:

(8, -5); x=8; y=-5

Step-by-step explanation:

i'll be solving via substitution

2x+3y=1; y=-2x+11

2x + 3(-2x +11) = 1

2x -6x +33 = 1

-4x = -32

x = 8

2(8) + 3y = 1

16 + 3y = 1

3y = -15

y = -5

(8, -5)

Check:

-5 = -2(8) + 11

-5 = -16 + 11

-5 = -5

A line is shown in the graph below.

Kay [80]

Answer:

-3/2

Step-by-step explanation:

One can read off the slope of the given line directly from the graph. As x increases by 3, y increases by 2. Thus, the slope of the given line is

m = rise / run = 2 / 3

Any line perpendicular to this given line has a slope which is the negative reciprocal of the slope previously found:

-1 3

Slope of perpendicular line = ------------ = - -----

2/3 2

This matches the first of the given possible answer choices.
